1 / 86 page The information in this document is subject to change without notice. DESCRIPTION The µPD78324 is a 16/8-bit single-chip microcontroller that incorporates a high-performance 16-bit CPU. The µPD78324 is one of 78K/III series. The internal capacity is significantly increased compared with the conventional µPD78322. A realtime pulse unit for realtime pulse control required in motor control, an A/D converter, a ROM, and a RAM have been integrated into one chip. The µPD78324 incorporates 32K-byte mask ROM and 1024-byte RAM. The µPD78323 is a ROM-less version of the µPD78324. Also, It is provided the µPD78P324 as an on-chip PROM product. Detailed information about product features and specifications can be found in the following document. µPD78322 User’s Manual : IEU-1248 FEATURES • Internal 16-bit architecture and external 8-bit data bus • High-speed processing by pipeline control and instruction prefetch • Minimum instruction execution time: 250 ns (with 16 MHz external clock in operation) • Instruction set suitable for control operations ( µPD78312 upward compatible) • Multiply/divide instructions (16 bits × 16 bits, 32 bits ÷ 16 bits) • Bit manipulation instruction • String instruction, etc. • On-chip high-function interrupt controller • 3-level priority specifiable • 3-type interrupt processing mode selectable (Vectored interrupt function, context switching function, and macro service function) • Variety of peripheral hardware • Realtime pulse unit • 8-channel, 10-bit A/D converter • Watchdog timer • Powerful serial interface (with an on-chip dedicated baud rate generator) • UART ····· 1 channel • SBI (NEC Standard Serial Bus Interface) • 3-wire serial I/O APPLICATIONS • Motor control devices Unless there are any particular diferences, the µPD78324 is described as the representative model in this document. © 1991 DATA SHEET µPD78323,78324 MOS INTEGRATED CIRCUIT 16/8-BIT SINGLE-CHIP MICROCONTROLLER ····· 1 channel The mark shows major revised points.
